Electro-Voice EVF-1152S/96 is a high-power, two-way loudspeaker system that can be used in a variety of applications where high-quality sound reinforcement is required. It utilises ND2B, a high-output 2-inch titanium compression driver, coupled to a Constant Directivity 90-degree x 60-degree waveguide. The SMX2151 15-inch woofer was developed using FEA optimisation for motor, suspension, and electrical design to ensure very low distortion, high efficiency, and maximum intelligibility at high SPL levels.
